The relationship between obesity and hypertension: an updated comprehensive overview on vicious twins.

Obesity is a growing global health concern, with a rapid increase being observed in morbid obesity. Obesity is associated with an increased cardiovascular risk and earlier onset of cardiovascular morbidity. The growing obesity epidemic is a major source of unsustainable health costs and morbidity and mortality because of hypertension, type 2 diabetes mellitus, dyslipidemia, certain cancers and major cardiovascular diseases. Similar to obesity, hypertension is a key unfavorable health metric that has disastrous health implications: currently, hypertension is the leading contributor to global disease burden, and the direct and indirect costs of treating hypertension are exponentially higher. Poor lifestyle characteristics and health metrics often cluster together to create complex and difficult-to-treat phenotypes: excess body mass is such an example, facilitating a cascade of pathophysiological sequelae that create such as a direct obesity-hypertension link, which consequently increases cardiovascular risk. Although some significant issues regarding assessment/management of obesity remain to be addressed and the underlying mechanisms governing these disparate effects of obesity on cardiovascular disease are complex and not completely understood, a variety of factors could have a critical role. Consequently, a comprehensive and exhaustive investigation of this relationship should analyze the pathogenetic factors and pathophysiological mechanisms linking obesity to hypertension as they provide the basis for a rational therapeutic strategy in the aim to fully describe and understand the obesity-hypertension link and discuss strategies to address the potential negative consequences from the perspective of both primordial prevention and treatment for those already impacted by this condition.
